Capacity Modes and Table Classes

With DynamoDB, users only need to think about having a good design along with the read and write throughput depending on the capacity mode of the table. Capacity modes determine how users are billed for the use of their DynamoDB tables, and they also affect how the table can scale.

To understand capacity modes, let us consider an analogy. Imagine you are running a restaurant.
